Android工程混淆打包：一個典型過程和示例文件

本例不含依賴工程的情況，如有依賴工程，請先導出為jar包再打包：

1. 基於Android 2.1以上版本；

2. 簽名的密鑰文件生成；

1）. 創建證書：keytool -genkey -alias mykey.keystore -keyalg RSA -keystore mykey.keystore 密碼同系統登陸密碼
3）. 查看證書庫：keytool -list -keystore mykey.keystore
4）. 導出到證書文件：keytool -export -alias mykey.keystore -file mykey.crt -keystore mykey.keystore
5）. 導入證書的信息：keytool -import -keystore mykey.keystore -file mykey.crt mykey.crt導入到名為mykey.keystore的證書庫中
6）. 查看證書信息：keytool -printcert -file mykey.crt
7）. 刪除密鑰庫中的條目：
keytool -list -keystore mykey.keystore
keytool -delete -keystore mykey.keystore -alias mykey.keystore
8）. 修改證書條目的口令：keytool -keypasswd -alias mykey.keystore -keystore mykey.keystore

3. proguard.cfg文件
